.To ALL WHoM IT MAY coNcERN:

Be it known that I, R. M. VAN SIGKLER, ofthe city, county, and State of New York, have invented a new and useful Improvement in Adjustable Roller-Frames for Elevator-Platforms; and Il do hereby declarethat the following is a full, clear, andexaet description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification, in which- Figure 1 is a top view of one of'my improved roller-frames.

Figure 2 is a vertical longitudinal section of the same, taken through the line zw, iig. 1..

f Figure 3 is a view illustrating the use of my improved frames.

Similar letters of reference indicate Acorresponding parts. Y

lVl'y lnvention'has for its object to furnish an improved attachment to lmy improved elevator, patented February 12, 1867, `so as to make it more convenient and elieient in use, and which may at the same time be used with other elevatonplatforms with equal facility and advantage; and it consists in the combination of the frame-rollers and pins or projections with each other, as hereinafter more fully described.

A is the frame, consisting of two side bars al, connected by two or more cross-bars a2. I prefer to make the frame A of iro'n, east solid in one piece; but the material of which itis made is immaterial. B are pins or `projections upon the'under side' of the frame A, which enter holes formed in the platform of the elevator for their reception. Two or more frames A should be used.upon the platform, according to its size, and several sets of holes for the'pins or prongs B should be formed, so that the frames may be arranged as may be most convenient, according as it may be desired. to take the-packages off at the sides or end ot' the platform. C are rollers, the journals of which revolve in. the side bars al of the frame A. By means of this device the packages may be placed upon or removed fromV the platform, either in tiering or lowering said packages-without lifting or turning them. In handling the packages either upon the tiers or upon the door, loose rollers or similar rollerfram-es may be used, as may be most convenient.

' I claim as new, and desire to secure by Letters Patent The sides a a, bearing the rollers C, when such sides are connected together by means of the cross-bars a", having the downward projections B, for receiving theframe upon .the platform of the elevator to prevent slip- 'ping and longitudinal movement, as .herein shown and described.

The above specification of my invention signed by me this 30th day of July, 1867.
